SPECIFICATION forming part of Letters Patent No. 242,090, dated May 24, 1881,

Application filed December 22, 1880. (Model.)

l enable others skilled Ain the art to which it appertains to make and use the same.

' The object and nature ot' my invention are to preserve thecrutch and prevent its destruction from the use of tacks or small nails, which are now used to secure the arm-pads to the crutch. The repeated driving of the tacks into the crutch frequently splitsit and renders it useless.

My invention obviates the necessity of using tacks or nails to secure the arm-pads to the crutch altogether, and instead ot' weakening 4the crutch it strengthens and makes it more durable.

It consists ot` a metal box, a detailed description ot whichis hereinafter given.

The drawing accompanying this specification, and which is made a part hereof, represents the top of a crutch, partly in section.

Ais the metal boxe; B, thehinged part; C, the cloth orlea therends of the armpads, D, ascrew, securing both 5 E, the crutchtop; a, the rivet or pintle on which the hinged part turns b, serrations oninside of hinged part; d,serrations on crutch-top.

The metal box is made from tWo and one half to three inches in length, and ot' width .and depth sufficient to pass easily over the crutch-top. Smooth rounded projections are formed on three outer sides, leaving the inner side or bottom of the box smooth and flat. These projections extend slightly upward from the inside when the box is in place on the crutch. On the outside a lid or hinged part is formed to t neatly inside the box, so that when in place on the crutch the outside presents a smooth surface. At the upper end of the box small holes are made through the rounded projections, and a corresponding hole through the rounded projection which forms one ofthe three sides, as above described. Through these holes inthe box and lid a metal rivet or pintle passes, upon which the lid turns. Serraticns are made in the lid or hinged part and corresponding serrations in the crutch-top. The cloth or leather ends of the arm-pads are passed over the top of the crutch and through the box, the ends of which areleft open to receive them. The vlid or hinged part is then closed on the outer side of the crutch-top and secured by a screw,
